Subscribed for one year and no problem so I thought, when time renew, the computer almost came to stop, I got it running, when I called their tech they said my computor had infested with hackers last few days, and to renew would cost me over $200.00 so they could clean it out, I said no, removed it and went to another antivirus program, which pulled up a virus, which Defender never found, quarenteened i I also added new version Zone alarm and computor purring along fine. Hackers can be anywhere, I felt it was a fixed deal, they push alot questionable products and feel disapointed that they did this way.
